# HX258EST

**HUAXIN** · Hall Sensor · SOT-23-3L

HX258EST from HUAXIN, in a SOT-23-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply input. Operating range 1.7 V to 5.5 V (absolute max 6 V). Bypass with 10 nF to GND close to the pin. |
| 2 | OUTPUT | output | Open-drain Hall switch output. Requires external pull-up (10 kΩ typical) to VDD. VOL ≤ 0.2 V at 0.5 mA sink; leakage IOFF ≤ 1 μA in the off state; max output current 1 mA. |
| 3 | GND | power_in | Device ground reference. |

## CAD (KiCad official)

- Symbol: `HX258EST`
- Footprint: `Package_TO_SOT_SMD:SOT-23-3`
- 3D model: SOT-23-3L (KiCad packages3D, STEP)
- 3D model files: `hx258est-etched.step` / `hx258est-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hx258est.step` / `hx258est.glb` are the bare package body.
